Zhao Di carefully picked up a piece of refined copper scrap that he had refined, put it into the small ding, covered the ding, and waited for the miracle to happen.

According to his previous research on the anti-heaven effect of Xiaoding, all spiritual objects that contain spiritual power themselves, but whose spiritual power is not in the most full state, are likely to upgrade their spiritual power to the peak in Xiaoding, that is, the maximum spiritual power determined by the material of the spiritual object itself. The more spiritual power you add, the longer it will take.

For example, the second pill and low-rank spirit stones can be upgraded into ordinary pills and high-grade spirit stones through Xiaoding. Dansha can also become more abundant. Then, this purified and broken refined copper is like Cidan, and it is possible that it will be promoted to ordinary refined copper by Xiaoding.

An hour later, Zhao Di, full of anticipation, opened the lid.

Sure enough, the spiritual power contained in the refined copper in the tripod has been greatly improved, and the color is also more brilliant. Compared with the few pieces of refined copper he carefully purified, this piece in the ding seems to be slightly better.

Although he didn't know if Xiao Ding could further improve the refined copper, Zhao Di didn't dare to continue the experiment, in case he cultivated the refined copper with amazing spiritual power and aroused the suspicion of Uncle Kuang, he would lose a lot because of a small loss.

He took this piece of refined copper from the small ding, and put in another piece of refined copper that had been quenched.

This time, more than half an hour later, he took out the fine copper in Dingzhong.

Zhao Di, who had already overused his divine sense, causing headaches and dizziness, finally put his mind at ease and slept beautifully.

This sleep was two days and two nights! Zhao Di, who had a good night's sleep, returned to his original consciousness. At this time, although there were only seven or eight days left before the one-month deadline, he still had half of the ore that had not been purified.

But Zhao Di, who had Xiaoding in hand, was not panicked at all.

He asked for his surname once and threw all the remaining ores in front of him, and then a "levitation" trick was struck, and these ores floated at a height in the center of the stone house. Then he injected a piece of spiritual power into the dragon head stone statues on both sides of the stone house with both hands, and from the open mouth of the stone statue, a pillar of fire the thickness of an arm erupted, burning directly on the ore, and after a while, it turned into a little droplet, still floating in the air.

Zhao Di didn't care whether the refined copper in the ore had been burned by the earth fire for too long, and he just used his divine sense to control the refined copper essence in it to gather into five or six small groups.

After spending a lot of effort, finally all the refined copper essence gathered into a ball, Zhao Di withdrew the spiritual power that controlled the earth fire, and the dragon heads on both sides of the stone house suddenly stopped erupting the pillars of fire.

At the same time, he was also a spiritual power sent into the dragon head of the spiritual spring at the west end of the stone house, and streams of spring water flowed out of the dragon's head, which soon filled the pool below, and then no more spring water flowed out.

Zhao Di controlled several balls of refined copper stock liquid suspended in the air, and quickly flew into the pool, and after a "zla" sound and a piece of white smoke rose, several pieces of refined copper appeared in the pool.

The whole process took Zhao Di about seven or eight hours, and he was already tired and sweating profusely by this time.

It's okay that the loss of spiritual power is good, he has always held a high-grade spirit stone in his hand, and he can replenish it at any time. It seems that the depletion of consciousness can only be slowly recovered through rest.

And his result was five or six pieces of refined copper material that was obviously lacking in spiritual power, and the color was a little dull. There was even a piece of it that was dark brown and had little spiritual power, which was too far from the golden yellow that the refined copper should have.

This is the result of refining too much ore at one time, and the divine consciousness is not refined enough at all.

But Zhao Di didn't care, anyway, he had Xiaoding. He cultivated a few pieces of refined copper scrap in Xiaoding for about half an hour, and then continued to meditate and rest.

The one-month deadline was coming soon, and Zhao Di confidently left the refining room with more than a dozen pieces of refined copper material.

Senior Brother Lu was already waiting in the stone corridor outside the refining room, and after Zhao Di and the other three came out of their respective refining rooms, the group of four left the stone corridor through the teleportation array, and continued to walk along the stone steps that they had walked in the direction of Baixu Hall.

Along the way, several people were silent. Zhao Di secretly glanced at Fang Fu and Ma Gao a few times, and found that they both showed uneasy expressions. Obviously, the results they have refined are not ideal.

The two of them couldn't see any expression on Zhao Di's face, there was no sadness or joy, and they were even more anxious in their hearts. When Ma Gao went to the refining room from this mountain road, he felt that it was too far and too long, but now he wished that this road would never end.

It's a pity that in his apprehensive mood, it seems that after a short period of time, several people came to Baixu Hall.

In the Baixu Hall, the slightly chubby Uncle Kuang was still sitting in the Taishi chair, closing his eyes and recuperating.

But this time was different, as soon as Zhao Di and the others stepped into the temple gate, he opened his eyes.

"How much refined copper has been extracted? This Uncle Kuang didn't ask about Zhao Di and the other three people's comprehension at all, but went straight to the topic to check the purification results. After all, the result of rhetorical theory and practical indulgence is obviously the latter being more direct and important.

The three of them took out the storage bag that originally contained the refined copper ore, poured the contents of the bag in front of them, and then looked at the refined copper material in front of the other two in unison.

Zhao Di also quickly glanced at it and found that both of them had only purified ** pieces of refined copper materials, and more than half of them were purified and broken scraps.

However, there were eleven pieces of refined copper in front of Zhao Di, of which only three were scraps, and this was a judgment.

The three people, including Zhao Di, all sank in their hearts, but the difference was that Zhao Di's heart sank, but there was no change on his face. He was worried that his performance was too good, and he was afraid of arousing the suspicion of this Uncle Kuang.

With Zhao Di's original intention, he originally wanted to be at the same level as the other two, not to be particularly prominent, but under his own control, he still miscalculated the refining results of the two. Unexpectedly, the refining skills of these two people were much worse than he imagined.

Ma Gao and Fang Fu were much simpler, and their achievements lagged behind Zhao Di in both quality and quantity, and their faces were full of shame and nervousness.

Senior Brother Lu and Senior Uncle Kuang on the side were both slightly surprised, obviously Zhao Di's results exceeded their expectations.

The fat man said in surprise: "Hey! This piece of refined copper material is well refined, very good!" After speaking, he picked up a piece of golden refined copper material in front of Zhao Di, played with it carefully, and at the same time piled up a bright smile on a few pieces of fat on his face, and said to Zhao Di: "It seems that you have a great talent for refining weapons, what is your name?"

"Senior nephew Zhao Di, Uncle Xie praised, this is the result of Uncle Shi's careful teaching. Zhao Di hurriedly slapped a sycophant that even felt numb.

"Well, Senior Nephew Zhao, tell me, what is the difference between you refining this piece of refined copper material and the other pieces in the process?" this Uncle Kuang nodded and asked with a smile.

Zhao Di gushed out the words that had already been prepared in his stomach: "Back to Uncle Kuang, after entering the refining room, the nephew first spent three days carefully studying the refining jade slip granted by his uncle, and after comprehending it, he began to refine and purify the refined copper ore. However, due to the fact that the firepower of the Earth Lung Fire was always not properly mastered, the first two times failed to refine the fine copper material. After the nephew rested for a while, he continued to refine, this time I don't know why, the fire of the lungs is extremely stable, and the longitudinal is relatively stable, and the nephew is also handy in refining, so he refines this piece of refined copper. But then, no matter how carefully the master and nephew worked hard, they could no longer purify this exactly the same refined copper material, and they were always slightly inferior. On the contrary, once because the consumption of divine consciousness was too large, he did not grasp the heat and proportion, and obtained a piece of refined copper scrap. ”

"What did you arrange for them to be a low-grade refining room?" Uncle Kuang listened to what Zhao Di said, and did not reply, but turned his head and asked Lu Wen.

Lu Wen nodded and replied, "Yes, Uncle Kuang." ”

"Well, it seems that you do have a great talent for refining weapons. Kuang Fatzi said to Zhao Di again, "The fire of the earth lungs in the lower grade refining room is indeed not very stable, and it is very rare for you to refine such a piece of high-grade refined copper material, even if I refine it myself, I may not be able to refine it." ”

This is said from the bottom of his heart. Indeed, with his current refining attainments, although it is the most preliminary raw material purification process, he does not dare to guarantee that he will be able to refine such a fine product once out of three times, let alone in the low-grade refining room where the firepower is occasionally unstable.

"Senior nephew Zhao, you have done a good job, Uncle Zhao and I are good at punishment, I must reward you well. Kuang Fatzi put the refined copper material in his hand into his arms, and said with a smile.
